provide an inclosing casing for boilers,

which will give a finished and an attractive appearance to the boilers, and which at the same time will provide an insulating cover for the boiler to confine the heat thereof and prevent wasteful dissipation of the heat.

For the purpose of disclosing my inven- LJtion, I have illustrated one embodiment thereof of the accompanying drawings, in which:

Fig. 1 is a side elevation ofa boiler embodying my invention, the (sectional) casing being shown partly in section; Fig. 2 is a front elevation thereof, showing the casing partly in section; Fig. 3 is a plan view of the casing; Fig. 4 is a transverse section of the top of the casing; Fig. 5 is a detailed section on the line 5-5 of Fig. 2. Fig. 6 is a detailed section on the line 6-6 of Fig. 1; Fig. 7 is an elevation of the front panel of the casingpFig. 8 is an elevation of a side panel of the casing; Fig. 9 is an elevation of the rear panel of the casing; Fig. 10 is a sectional view on the line 10-10 of Fig. 3; Fig. 11 is a sectional view on the line 11-11 of Fig. 3; Fig. 12 is a sectional view on the line 12-12 of Fig. 7; Fig. 13 is a sectional view on the line 13-13 of Fig. 8; F ig. 1% is a detailed elevation of one corner of the side panel; Fig. 15 is a sectional view on the line 15-15 of Fig. 8; Fig. 16 is a detailed sectional view on the line 16-16 of Fig. 8, and

in eflect one complete panel, although formed of a plurality of sections. The material at the top and two side edges of the panel is bent back upon itself as at 7 and then at right angles to form a flange 8 at the top and on the two side edges of the panel. Within this flange, which extends around the edges, except at the bottom thereof, is mounted a suitable insulating material 9, which maybe in the form of asbestos or any other desirable heat insulating material. The front and rear plates at each edge, are bent backwardly to form'the right angle lip 10 and on each of the side edges of the front and rear plates and are secured preferably by spot welding, an angle member 11, one leg 12 of which extends parallel with, but is spaced apart from the flange 10. These front and back members are provided with suitable openings therein to accommodate the fire doors, cleanout doors and smoke-boxes and the like, and if desired, these sections may be split as illustrated in Fig. 9 so that, the parts may pass over the projections and then connect together by bolts 13, which 1 pass through inturned flange 14. i

The top panelis formed of two sections of sheet metal 15 and16, these sections being adapted to overlap along the center line and to this end the metal of the section 15 is turned back upon itself as at 17 and then inwardly to form an angled flange 18 and the material ofthe opposite section 16 is turned down as at 19 to form an abutting flange. Each section has secured on each edge angle bars which are secured in position preferably by spot welding, and one leg 20 of the bars extends parallel with, but is spaced apart from an inturned flange 21 of the top. Suitable openings 22 are formed in the abutting sections at the top to accommodate steam pipes or the like.

The underfaces of the two top sections are lined with suitable insulating material in a manner similar to the two side panels.

In assembling the parts in position, the two side panels are placed against the sides of the boiler. It will be noted that these two side panels are provided at their bottoms front 7 portion of the angle members 23 so that, it will be locked against longitudina displacement. The front edges of thetwo side members take into the space between the flange 10 and the-legs 12 of the angle mem bers and are thus locked against transverse displacement. Therear member is similarly placed in position. Thus interlocking the parts" thus far assembled so that, the side members are prevented against displace ment and the end members, at least, their bottomsare" locked against displacement with respect to their side members. After the sides and ends are assembled, the two top sections are placed in position so that, the upper edges of the sides and end sections take into the space between the angle legs 20 and inturned flange 21, thereby securely interlocking all of the parts together and forming a rigid self-supporting, selflo'cking, inclo'sing casing, which may be assembled without the use of interlocking bolts, and which will remain in position so long as necessary, but which may be disassembled and removed from the boiler with out the use of tools ofanylkind.

I claim as my invention: 1. 'A'boiler casing comprising side panels and end panel's,,said side panels having-at their bottom'corners i'nturned end members provided with upwardly projecting flanges extending at right angles to the side panels and said end panels having at theiredges a pair of spaced apart flanges adapted to embrace the edg'e'sof the side panels to prevent lateral displacement thereof, the bottom edges of said end panels being constructed-to be embraced by said upturned flanges on the side panels'to prevent relatively displacement 7 between the panels longitudinally.

2. A boiler'casing comprising side and end the front and rear ends of the panels, end panels having inturned' flanges at its edges and having secured thereto angle irons, one leg of the irons being adapted to extend parallel with, but spaced apart from the inturned flange, and a cover member havingits edges turned down to form downwardly extending flanges and having secured to its edges angle irons havingsone leg parallel with said downturned flange and spaced apart therefrom, said end panels being adapted, when assembled to engage at their loweredges behind the upwardly extending legs of the inturned ends of the angle bars, secured at the lower edges of the side panels, the edges of said side panels being adapted to engage between the angle bars and flanges on the end panels and the top edges of the side and end panels being adapted to fit between the flanges and angle bars on the cover member, whereby all of said parts are interlocked into a rigid structure. l

4:. A boiler casing comprising side and end panels, the end panels having inturnedspaced apart flanges at their edges adapted to embrace the edges of the side panels to prevent lateral displacement thereof, and a cover member including a pair of sections; each'having downwardly extending spaced apart flanges at'its outer edges adapted to embrace the upper edges of the end and side panels.

In witness whereof I, WILLIAM H. Curr, have hereunto set'my. hand at Terre Haute, Indiana, this 30th day of November, A. D; one thousand nine hundred and twenty eight.
